Traits D - F

Daredevil

Applies a buff when the Sim is doing anything intense, especially being around or on fire. Changes many interactions to an "extreme" version (such as "Take Extreme Shower Until Extremely Clean"), but this does not affect animations or interactions at all.

This trait is incompatible with Coward.

Disciplined

Increases the XP rate of the Martial Arts skill.

This trait is incompatible with Couch Potato.

Dislikes Children

Reduces the relationship gain rate with toddlers and children, and applies a debuff when a toddler or child is nearby. This applies to the Sim's own kids, so this Sim will have a tough time being a parent.

This trait is incompatible with Childish, Family-Oriented, and Nurturing.

Diva

Adds a host of self-interactions that allow the Sim to compliment herself, slightly increasing the fun or social meters even without another Sim around. Gains a buff when the social situation favors the diva, and gains a buff when the Sim has caused some sort of anti-social situation. (In other words, the Sim gains a buff when he or she is the center of attention.)

This trait is compatible with all others.

Dog Person

Increases relationship gain rate with all dogs, and applies a buff when a dog is nearby. The gain is stronger than in the Animal Lover trait, but applies only to dogs and not the other animals.

This trait is incompatible with Animal Lover, Cat Person, Equestrian.

Dramatic

Adds special animations, buffs, and debuffs when the Sim experiences certain everyday interactions. All effects are minor, but can add some variety to families.

This trait is compatible with all others.

Easily Impressed

Applies a buff when any Want is fulfilled. Increases the relationship gain rate when this Sim is the target of positive one-way social interactions (such as being told a joke or being bragged to). A Sim with this trait will always accept a "Brag About" social interaction.

This trait is incompatible with Snob.

Eccentric

Increases the XP gain rate of the Inventing skill. Also increases the chance an invention will be created successfully, and that a new invention type will be unlocked as a result.

This trait is compatible with all others.

Eco-Friendly

Applies a buff when the Sim is carpooling, riding a bike, recycling his trash, growing his own food, and so on. Applies a debuff when the Sim drives somewhere or takes a taxi by himself, wastes food, or takes a bath (because it's a waste of water).

This trait is incompatible with Hates the Outdoors.

Equestrian

Increases the relationship gain rate with horses, and applies a buff when a horse is nearby. The gain is stronger than the Animal Lover trait, but applies only to horses and not other animals.

This trait is incompatible with Animal Lover, Cat Person, and Dog Person.

Evil

Applies a buff when the Sim does any negative social interaction to another Sim, and has several special negative social interactions as well. Also removes the debuff if the Sim is in an unlit room.

This trait is incompatible with Good.

Exciteable

Increases the effects of all buffs, with no effect on debuffs. A great all-around trait, especially if you can fulfill Wants regulartly.

This trait is incompatible with Brooding and Grumpy.

Family-Oriented

Increases the relationship gain rate with any related Sims (interations with unrelated Sims are unaffected either way). Sims with this trait also have wants that revolve around related Sims, and rarely have wants that would encourage them being unfaithful.

This trait is incompatible with Dislikes Children, but not Committment Issues. However, a Sim with Family-Oriented and Commitment Issues tends to want to divorce and remarry, making it a challenge to raise kids.

Flirty

Greatly increases the chance that any flirt-type social interaction will pass. It's best for Sims looking to have many romantic prospects, but it's workable with a spouse too.

This trait is incompatible with Shy and Unflirty.

Friendly

Increases the relationship gain rate with all Sims (including animals), and slows the relationship decay rate. Pairing Friendly and Charisma will allow a Sim to keep dozens of friends without much effort.

This trait is incompatible with Mean Spirited.

Frugal

Allows the Sim to clip coupons from the newspaper, allowing them to save money when shopping at stores (though not in Buy Mode). It's not a good trait in the long-term, but for Generation 1 Sims, it may help them get off the ground faster.
